Fascinating article with an unexpected reason why Afghanistan fell so fast. Don't know how much I agree with it, but at the very least it makes some solid points.
Did America just lose Afghanistan because of WhatsApp? – Preston Byrne
So what the hell happened?

WhatsApp is an American product. It can be switched off by its parent, Facebook, Inc, at any time and for any reason. The fact that the Taliban were able to use it at all, quite apart from the fact that they continue to use it to coordinate their activities even now as American citizens’ lives are imperiled by the Taliban advance which is being coordinated on that app, suggests that U.S. military intelligence never bothered to monitor Taliban numbers and never bothered to ask Facebook to ban them.
